A refined late-Cryogenian – Ediacaran earth history of South China: Phosphorous-rich marbles of the Dabie and Sulu orogens

摘要

Highlights?New stratigraphic and carbonate-C isotope data link the Susong-Haizhou Groups (Dabie-Sulu orogens) correlate to Ediacaran of Yangtze Block.?Sulu Orogen pebbly schist and P-rich rocks correlate to Nantuo and Doushantuo Formations.?Dabie Orogen marble and P-rich rocks correlate to Dengying Formation.?Yangtze Block Ediacaran carbonate platform extended into the Dabie-Sulu orogens.?Findings support models of the Tan-Lu fault being a continental-scale tear fault.AbstractThe late-Cryogenian – Ediacaran geological framework for South China is constructed principally from sedimentary successions preserved in the central and western regions of the Yangtze Block. New stratigraphic and carbonate-carbon isotope data allow us to extend that framework into the exhumed HP-UHP subduction complexes of the eastern Dabie
